I recently learned that, following using oxygen only overnight for almost a decade, those times it wasn’t used may have been behind my newest diagnosis of heart failure? Or, does COPD contribute to that?
HFpEF —heart failure with preserved ejection fraction — (unknown, and following a prior in-house cardiac 3-day workup, where my heart was said to be just fine), revealed only incidentally by a blessedly wise cardiologist ordering a right heart cath), meant my heart was stiff, having difficulty passing newly oxygenated blood.
So, my inexplicable breathlessness for years wasn't only COPD? Even with CPAP, I\it still dips below 88%, but for not as long…
Thus, the new switch to CPAP — but without oxygen — has me nervous!
